Hi PLL. Well, everyone's experience is different. Also a lot of folks' experience is on older rim shapes
The older style aero rims with the "pointy" trailing edge did tend to get blown around quite a bit. This is why you used to see so many folks running a smaller rim section in front.
However, the newer aero shapes with the "fat" trailing edge really are better in the wind. I'm no aerodynamics expert but the explanation given by Zipp is that the center of effort is moved behind the hub so the wheel sort of "self corrects" They explain that the pointy trailing edge rims failed to account for the fact that the trailing edge in the front becomes the LEADING edge at the back of the wheel.

Sunday our tri had a fairly long section with the 10-15 mph gusting wind right off the lake at a 90 degree angle. My friend had REGULAR non aero wheels and felt quite "out of control" I had my Zipp 404 Firecrest with about a 60 mm deep section. Did I feel the wind a bit...yes. But no more than any other wheel and I certainly didn't ever feel like I had to adjust my riding to compensate.

If I was a bit lighter and rode in a "gusty" windy area, I'd likely take the conservative approach and get the Firecrest 303 which is a bit smaller in section. Darn near as aero.

They're not cheap. I'll always recommend renting a set to see if they are for you. As you can tell, I'm firmly a believer.
